MEANS FOR ll/IGORING SHIPS.

Specification of Letters Patent.

Patented Oct. 4, 1921.

Application filed November 30, 1920. Serial No. 427,322.

To all whom it may concern:

Be it known that I, FRANCIS N. B. wlVAL- TON, a SLIbjBCb of the King of Great Britain,

residing at San Francisco, in the'county of San Francisco'and State of California, have invented certain new and useful'lmprovements in Means for Mooring Ships; and I do hereby declare the following to be a full, clear, andexact description or the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to means for moorin ships.

%heobject of the present invention is to improve the means for mooring ships and to provide a simple, practicaland efiicient construction equipped with a single hawse or pipe adapted to accommodate both chor cables and capable, when it'is desired to moor a ship of enabling the shackle to be readily applied on deck to the cables, whereby it may be easily handled and readily placed in position and attached to the cables and also removed from the same without employing the large number of m n which are required when separate hawses or pipes are employed for the anchor cables;

It is also an object of the invention to provide a device of this character capable of enabling time and labor to be saved in applying the swivel to'the'anchor cables and in removing the swivel from the same in mooring nd unmooring so that comparatively no time will be lost .in such operation.

With these and other. objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details or" construction, with in the scope of the claims, may be resorted to without departing from the pirit or sacrificing any of the advantages or" the invention.

In the drawings:

Figure 1 is a plan view of a portion of a ship provided with mooring means constructed in accordance with this invention, the anchor cables being continuous from the capstans or cable winches to the anchors preparatory to receiving a swivel.

Fig. 2 is a similar view, the anchor cables being uncoupled and held by slips and the swivel being in position ready for attachment.

Fig. 3 is a plan view,- the swivel being appliedto the anchor cables and being arranged in operative position.

1 1g. 4 is an enlarged detail view of the swivel.

Fig. 5 is a detail front elevation of a portion of the ship illustrating the construction of the central hawse or pipe.

Fig. 6 is a detail sectional view taken longitudinally of the hawse or pipe.

Like numerals of reference designate corresponding parts in all the figures of the drawings. In the accompanying drawings, in which is illustrated the preferred embodiment of the invention, the ship mooring means comprises in its construction a centrally arranged hawse pipe 1 extending centrally through the bow of the hull of the ship and comprising an arched top 2 and bottom side groove or runways 3 and having a centrally arranged longitudinally disposed ridge 3 rounded at the top as clearly illustrated in Fig. 5 of the drawings and adapted to separate the grooves or runways and maintain the anchor cables clear of each other so that a common hawse pipe may be employed for the cables of the starboard and port anchors. The cables are composed of sections which are connected by coupling shackles 6 so that the sections or shackle links of the cables maybe readily separated for the in troduction of a swivel? when it is desired to moor a ship. The swivel 7 is composed of swivel members 8 and 9, triangular coupling plates 10, plain links 11 and Band shackles 13. The shackles are located at one end of the swivel for connecting that end with the cable sections and the plain links at the other end of the swivel are for connecting the swivel with the sections of the cables having the shackles.

The anchor holding portions of the chains or cables are held by slips 14 anchored at 15 on the deck of the vessel at spaced points and provided at their free ends with hooks 16 for engaging links of the cables. extend around capstans or winches 17 and pass into the chain lockers 18 which are located in rear 01 the slips, the cables being separated between the winches and the slips as clearly shown in Fig. 2 of the drawings. After the swivel has been applied to The cables 7 the cables, the latter are drawn taut and are heaved sufliciently to release the slips which are detachedfrom the cables. The cables are then paid out until the swivel passes through the hawse or pipe and occupies a position close to the surface of the water, the weight of the chains being suflicient to maintain it in such position.

When the vessel is to be moored she first drops out one of her anchors and checks the headway of the vessel with the engines and finally stops the same and at the desired distance from the said anchor the other anchor is dropped and by operating the winch of the cable of the first anchor the ship is brought to a central position between the anchors. The swivel is 'then coupled to the cables in the manbe completed, that it may be effected by very few hands and that the swivel may be quickly applied to the cables and removed therefrom so that no time is lost in mooring and umnooring a vessel. The ship mooring means will be. found of increasing advantage owing to the 'increaseof shipping the necessity of mooring in small harbors and other places where room is a desideratum. It will also be clear that all of the slow, diflicult and'dangerous operation of applying a swivel to cable chains passing through separate hawse pipes is eliminated and that the particular constructionof the hawse pipe will prevent the cables from interfering with each other, The hawse pipe, which is approximately arcuate cross sectionally, is of a-size to permit the swivel to pass through it in paying out or taking in the cables and when the swivel is in the position shown in Fig. 3 at the surface of the water, the ship will swing on the swivel between the mooring anchors. The common hawse pipe Wlll also render 1t much easier to take out the turn in a cable caused by a ship swinging with the tide. Also the coupling shackle 6 and the large plain'links 19 ofthe sections of the chain pass freely through the hawse pipe.

What is claimed is:

1. In a'ship mooring means, the combina- 2. In ship mooring means, the combination with a pair of anchor cables, of a hawse pipe common to and receivingboth of the cables, said hawse pipe being arranged centrally of a vessel at the bow thereof, and having separate grooves or runways at the bottom to receive the cable chains.

3.'In ship mooring means, the combination with a pair of anchor cables, of a hawse pipe common to and receiving both ofthe cables, said hawse pipe being arranged centrally of a vessel at the bow thereof, and having separate grooves or runways at the bottom to receive the cable chains, said hawse pipe being also provided with a longitudinal rib interposed between the grooves or runways and rounded at the top portion.

4. In ship mooring means, the combination with a vessel provided with chain lockers and having winches, and cables extending from the lockers around the winches, of a central hawse pipelocated at the bow and .receiving both of the cables, and means for holding the cables in rear of the hawse pipe 'for enabling the same to be uncoupled on the vessel, and a swivel adapted to connect the uncoupled cables and to be applied to the same on the deck of the vessel. 7

5. In ship mooring means, the combination with a vessel provided with chain lockers and having winches, and cables extend ing from the lockers around the winches, of

a central-hawse pipe located at the bow and receiving both of the cables, slips arranged at spaced points at'opposite sides of the cables and consisting of short chains anchored at one end and provided at the other end withhooks for engaging the cables, said slips permitting the cables to. be uncoupled inrear of them, and a swivel adapted to be applied to the cables after the same have been uncoupled and to be handled on the deck of the vessel, said hawse pipe being of a size to permit the swivel to pass through it. y a V In testimony whereof I afiix my signature FRANCIS W. .B. WALTON.
